Overview

PAB3D solves the three-dimensional Reynolds-averaged Navier-Stokes equations with a finite-volume formulation on structured multi-block grids. The PAB3D code was developed at NASA Langley Research Center under NASA Contract NAS1-19831 and the United States Government retains certain rights. The National Aeronautics and Space Administration, Langley Research Center (NASA LaRC), acting under the authority of the National Aeronautics and Space Act of 1958, as amended, and Analytical Services & Materials, Inc. (AS&M), jointly executed a Memorandum of Agreement (MOA) in order to foster commercialization of the PAB3D software code.

Initially developed to predict simple internal and external performance of nozzle-afterbody configurations, the code has evolved to predict complex flow in mixer-ejector nozzles, thrust vectoring, multi-species jet mixing, and propulsion installation with a variety of aerodynamic configurations. The PAB3D code is part of the CFD Resources at NASA Langley. The flow solver has a robust (production quality) two-equation k-epsilon turbulence models with anisotropic algebraic Reynolds stress models. Large Eddy Simulation LES and Partially Averaged Navier-Stokes Equation has been recently added to the code.PAB3D also has the capability of modeling standard air real-gas effects. The code is capable of working in multiprocessors and distributed computer systems (CFD on Inexpensive Clustered Computers). This code has been used to simulate complex aerodynamic flow configurations and is currently being used in several national programs such as:
